Quickly finding the quintuple of -4

To quickly find the quintuple of -4, you multiply -4 by 5. This operation means you are taking the original number -4 and increasing it fivefold. Multiplying by 5 is the same as adding -4 to itself five times, which simplifies the calculation and gives the total amount in just one step. When you calculate -20 by multiplying -4 by 5, you receive the quintuple of -4. This approach is efficient and applies to any number you choose for -4. For example, if -4 were 7, then 7 multiplied by 5 would give -20 as 35. This method allows you to quickly find five times any number using simple multiplication.
